I take it neither /proc/cpufreq nor /sys/devices/system/cpu/cpu0/cpufreq exists on your system?

[Comment 4 jieryn 2006-02-05 16:35:29 UTC]

neither of those files exist on my system.. how to get them?

Reopening.

AMD64 herd: Can you confirm that the CPU in question (AMD Athlon(tm) 64 Processor 3200+) supports setting different CPU frequecies?

I'm getting this bug as well, but on x86 (Pentium M).

CONFIG_CPU_FREQ=y in my .config, and I was using the conservative governor, but in wanting to change to something else, I installed cpufreqd and ran into this bug.

I have neither /proc/cpufreq nor /sys/devices/system/cpu/cpu0/cpufreq, but I used to on a similar fresh install 6 months ago.

i filed a bug for this over at the linux kernel bugzilla:

http://bugzilla.kernel.org/show_bug.cgi?id=6063

[Comment 9 Edward Ocampo-Gooding 2006-02-12 20:03:54 UTC]

Regarding the x86 bug:

Setting
CONFIG_X86_SPEEDSTEP_CENTRINO=y
CONFIG_X86_SPEEDSTEP_CENTRINO_ACPI=y
CONFIG_X86_SPEEDSTEP_CENTRINO_TABLE=y
CONFIG_X86_SPEEDSTEP_ICH=y

fixed my problem (setting anything other than CONFIG_X86_SPEEDSTEP_ICH wasn't self-evident to me)

Will track upstream bug report, thanks.

[Comment 11 Luca Guglielmetti 2006-12-31 06:51:08 UTC]

Is this bug really solved? I still have this problem with linux-2.6.19.* and linux-2.6.18.*

(In reply to comment #9)
> Setting

where have you found this option? with linux-2.6.19.1 if I search "CENTRINO_ACPI" in "make menuconfig" I get this:

if I search CENTRINO_ACPI
 Symbol: X86_SPEEDSTEP_CENTRINO_ACPI [=n]

but I'm unable to enable the X86_SPEEDSTEP_CENTRINO_ACPI option
